Title: Method and sensor for detecting dew condensation
Inventor: YOSHIDA KENICHI
IPC: G01N21/47
Filed: 1981-04-28
Abstract: PURPOSE:To detect the state of dew condensation surely by preventing errors owing to fluctuations in a light source and a photodetector by such constitution wherein the light transmitted through an object to be inspected is kept cut on the optical axis during normal time and the output of the photodetector is obtained by the scattered light of dew condensation when dew condenses. CONSTITUTION:Light is irradiated to the surface of a transmittable object to be inspected, for example, window glass 12, from a spot light source constituted of a light source 10 and a pinhole 11, and the light transmitted through the same is kept shut off with a mask 13 at all times, so that the output of a photodetector 14 is kept zero. When dew condenses on the glass 12, the light scattered by the dew is detected with the photodetector 14, and the state of dew condensation is measured with a measuring device 15. Since the output of the photodetector 14 is kept zero in the non-condensation state, errors owing to the level fluctuations of the light source, etc. are prevented and the dew condensation state is detected surely.

Title: Method and device for controlling supply of absorbent to wet type desulfurization equipment
Inventor: ISHIGURO OKIKAZU
IPC: B01D53/77
Filed: 1990-03-14
Abstract: PURPOSE:To determine the supply of an absorbent in consideration of the variations of pH and to secure stabilized desulfurization performance by setting a fuzzy computing element for correcting the supply demand of the absorbent using fuzzy inference. CONSTITUTION:The fuzzy computing element 20 is actuated to determine the pH correcting supply demand using the deviation signal between the value measured by a pH meter 3 and the command and the fuzzy inference by the rate of change of the deviation signal. Consequently, when the quasi-whole amt. is oxidized, the pH is decreased below the command even by increasing the pH correcting supply demand. However, the pH correcting supply demand of the absorbent is further increased in this case by the output signal of the computing element 20, the process is repeated until the pH reaches the target value, and hence the pH is kept close to the target value and not greatly deviated from the target value.

Title: Circuit for detecting level of digital signal
Inventor: ODAGIRI YASUSHI
IPC: H04L69/40
Filed: 1985-03-29
Abstract: PURPOSE:To relieve the load of a microprocessor and to improve the processing capability by detecting surely a level change in a digital signal such as a line state signal without being affected with an external disturbance such as noise and allowing the microprocessor to read the digital signal only when the level change is caused. CONSTITUTION:A shift register 12 applies outputs Q1-Q4 being the result of the line state signal retarded by one clock CLK's content to a state effectiveness detection circuit 13. When the levels of the outputs Q1-Q3 are all equal, an 'H' level signal G is outputted from an OR gate 132 and it shows that the line state signal B is constant for three clock periods. On the other hand, the outputs Q3, Q4 are inputted to an EX-OR gate 133. When both the signal levels differ, the 'H' level signal H is outputted and it shows that a level change exists in the line state signal B. The microprocessor 11 fetches a detection signal only when the level of the line state signal B has a change and controls a buffer 16 to read the state signal B.

Title: Schottky barrier diode
Inventor: TANBARA HIDEO
IPC: H01L29/47
Filed: 1979-05-25
Abstract: PURPOSE:To provide high withstanding voltage without causing deterioration to the forward direction characteristics, by forming a ring-shape (or annular) low- density impurity region on the surface of a semiconductor substrate and also a Schottky-barrier-making metallic film in the inside including the surface of the region. CONSTITUTION:An annular p region 2 is formed with an n-type imputiry on a main side surface of a p-type Si semiconductor by driving ion to such an extent as not to cause type of electroconductivity to be reversed. A Schottky-barrier-making metal, such as a film 4 of W, is formed on the surface of this region 2. By doing so, in the center section which acts as the Schottky barrier, the forward-direction rising characteristics will not be deteriorated just because of keeping density of the impurity. And for the surrounding areas where power concentration can be easily caused by a high impression voltage, high withstanding voltage can be achieved by lowering density of the impurity.

Filed: 1995-03-23
Abstract: PURPOSE: To reduce the thermal stress of a steam turbine rotor to enable the restarting in a short time by raising an load on a gas turbine and a temperature of exhaust gas when a difference between the temperature of main steam and the steam turbine rotor is large. CONSTITUTION: Along with the shift to load shut-off running or in-plant single running A, the exhaust gas temperature 21 of a gas turbine 4 is abruptly lowered and the main steam temperature 22 is abruptly cooled, provided that the steam turbine rotor temperature 23 is gradually lowered by the natural radiation. Before the ventilation to a steam turbine 14, permission C of increasing a load on the gas turbine 4 is given to raise an exhaust gas temperature 21. Thus, after a difference between the main steam temperature 22 and steam turbine rotor temperature 23 is set within a predetermined range, the ventilating permission B is given also to the steam turbine to raise loads on the gas turbine 4 and steam turbine 14, and complete restarting. Thus, the thermal stress of the steam turbine rotor is sufficiently reduced and the restarting time can be shortened.
